The picture showed a script called Batman Vs. Superman writtenby David S. Goyer and Zack Snyder, based on Batman: The Dark Knight Falls by Frank Miller and Klaus Janson. That book is, of course, the fourth and final chapter in the epic The Dark Knight Returns that pits Batman against Superman in the most impressive smackdown ever.

Earlier this year, Snyder introduced the sequel to Comic-Con crowds with Harry Lennix reading a passage from this issue. ”I want you to remember, Clark, in all the years to come, in all your most private moments, I want you to remember my hand at your throat. I want you to remember the one man who beat you.” However, he added that the film would not be an adaptation of that classic, which has only recently been animated as a two-part film along within elements finding their way into The Dark Knight Rises.

While the news is probably a publicity stunt, especially given that the Canadian popster is set to appear on Funny or Die shortly, Warner will have managed to take the heat off Affleck. If he is cast as Robin, he would at least as hated as Jason Todd by everybody over the age of 15.

The untiled sequel to Man of Steel, starring Henry Cavill as Superman and Ben Affleck as Batman, will hit cinemas on 17 July 2015 from Warner.
